You should look into the caselabs Magnum M8 case:What I would give for an 11-12 inch wide case, so I could put a pair of 360 radiators, on the floor.
Instead of the slim chance that I might go hptx, and there isn't really that much of a point since you can't Overclock sb-E on that chipset.... so not quite the enthusiast product.
